Basic (but not to me) Light switch question

So I'm replacing a regular light switch with a motion sensor switch and it should be straight forward connecting like wires to like. The new switch has two black wires a green (ground) wire and a bare (also ground) wire. When I pulled the old switch out of the wall however, I was staring at 2 white wires, 2 black wires and a red wire. Can't seem to find any info online. Any help with this is greatly appreciated as I am not looking for a shocking experience ;-)

There should have been only 2 black or red wires connected to the switch. Wasn't that the case?

Just hookup 2 wires connected the switch.

You said that you are replacing a "regular" switch, and I assume that you mean a conventional toggle one, but is it possibly a three way switch? Is it marked "ON/OFF"? Are there any other switches on that circuit? How are the original wires connected? And welcome by the way.

That device requires both the green and ground wire be connected to a ground.
Make sure you have a ground there.
